Game Informer has a great interview with Persona 5’s director, Katsura Hashino about how the next entry of Persona will distinguish from previous entries.
From the article:
Each of the characters, including the protagonist, has the mindset that – for one reason or another – they no longer have a place where they belong in society. So when they get a hold of the Isekai-Navi [note: Japanese version term] which allows them to enter another world and steal the malicious intent from others’ hearts, they find new kinship and a sense of belonging in becoming these “phantom thieves,” and throw themselves headlong into helping others and reforming society with their own hands. The ones that stand in their way are the adults – in other words, the traditional authority figures who dictate every aspect of these teenagers’ lives. And in Persona 5, the story takes a different spin: Rather than getting drawn into a strange case, the team throws themselves into the fray. Through their actions, they draw the attention of an even greater enemy… That’s how the game sets in motion.
These characters are vastly different than anything we’ve seen in the series yet, chasing danger head first, instead of falling into it.
Persona 5 was originally set to launch in 2015 but Atlus has delayed it until summer of 2016.
